Title:
POWER STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2017045660
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent a member at the inside of a power storage device from being deteriorated.SOLUTION: A power storage device 100 includes a case 1, an electrode assembly 3, an electrode terminal 7, a current cutoff device 10, and a sealing plug 15. The electrode terminal 7 connects the interior and the exterior of the case 1, is provided with a staking section outside the case 1, and includes a through hole. The current cutoff device 10 switches the electrode terminal 7 and the electrode assembly 3 from a conduction state to a non-conduction state by a deformation plate that operates when pressure in the case 1 exceeds a predetermined value. The deformation plate covers the through hole of the electrode terminal 7. The sealing plug 15 is made of a resin, and is inserted into the through hole of the electrode terminal 7.SELECTED DRAWING: Figure 1
